Basically all i know is that carbon and silicon have similiar atoms because they both have 5 protons, and the periodic law states that atoms that have similiar composition have similiar characteristics. Help me out.

I know you can't really know that well without more information, but I'm just wondering if its likely I'll have this too. My father had fully grey hair by the age of 26...as his son is it likely I will too?

does that mean it also happened hundreds of years ago?

This article http://news.yahoo.com/s/nm/20061017/sc_nm/space_galaxy_dc says :

"A seemingly violent collision of two galaxies is in fact a fertile marriage that has birthed billions of new stars"

and

"The image serves as a preview for the Milky Way's likely collision with the nearby Andromeda Galaxy, about 6 billion years from now"

but it doesn't say what effect it might have on life on Earth. I would've thought the new forces of gravity between all the nearby bodies would wreak some kind of havoc. Any ideas?

(our sun might have died out before then anyway but let's just assume it doesn't for the sake of the question)

1. Which of the following does NOT accurately describe a characteristic of gases?
a) Gas molecules can be "squeezed together" to fit into a container.
b) The gas we exhale expands out continuously into the atmosphere.
c) The vapors of two immiscible liquid (liquids that do not mix together, but form separate layers) will mix completely
d) If a large container is filled with a small amount of gas, the gas will occupy only a portion of the container.
e) One must include the temperature, pressure, volume occupied and number of moles of molecules to completely describe a gas.

2. Convert 699 torr to atm, mmHg, kPa
